Modular hip exoskeleton improves walking function and reduces sedentary time in community-dwelling older adults

Numerous studies showed that postural balance improves through light touch on a stable surface highlighting the importance of haptic information, seemingly downplaying the mechanical contributions of the support. The present study examined the mechanical effects of canes for assisting balance in healthy individuals challenged by standing on a beam. Sixteen participants supported themselves with two canes, one in each hand, and applied minimal, preferred, or maximum force onto the canes. They positioned the canes in the frontal plane or in a tripod configuration. Statistical analysis used a linear mixed model to evaluate the effects on the center of pressure and the center of mass. The canes significantly reduced the variability of the center of pressure and the center of mass to the same level as when standing on the ground. Increasing the exerted force beyond the preferred level yielded no further benefits, although in the preferred force condition, participants exploited the altered mechanics by resting their arms on the canes. The tripod configuration allowed for larger variability of the center of pressure in the task-irrelevant anterior–posterior dimension. High forces had a destabilizing effect on the canes: the displacement of the hand on the cane handle increased with the force. Given this static instability, these results show that using canes can provide not only mechanical benefits but also challenges. From a control perspective, effort can be reduced by resting the arms on the canes and by channeling noise in the task-irrelevant dimensions. However, larger forces exerted onto the canes can also have destabilizing effects and the instability of the canes needs to be counteracted, possibly by arm and shoulder stiffness. Insights into the variety of mechanical effects is important for the design of canes and the instructions of how to use them.     

多功能套针浮刺疗法治疗神经根型颈椎病——一项随机对照观察研究＊

目的 评价多功能套针浮刺疗法对神经根型颈椎病的临床疗效。方法 选取256例神经根型颈椎病患者，按随机数字表法分为观察组与对照组各128例。观察组应用多功能套针浮刺疗法进行干预，对照组为常规针刺治疗。两组患者均治疗7天。分别于治疗前后观察两组患者的简化McGill疼痛问卷（SF-MPQ）、国际标准颈椎功能障碍指数（NDI）和田中靖久颈椎病症状20分法量表评分，并于治疗结束后3个月观察复发率。结果 两组患者治疗后的SF-MPQ量表评分、NDI量表评分及田中靖久颈椎病症状20分法评分与治疗前相比均有改善（P<0.05），且观察组优于对照组（P<0.05）；两组患者于治疗后3个月随访，SF-MPQ量表评分与治疗后相比均有改善，且观察组优于对照组（P<0.05）；观察组临床疗效总有效率为96.88%，愈显率为81.25%；对照组总有效率为78.13%，愈显率为46.88%，观察组优于对照组（P<0.05）。结论 应用多功能套针浮刺疗法治疗神经根型颈椎病临床疗效显著，见效较快，可有效降低其复发率，且作用稳定，效果持久，值得临床推广应用。

术前控制营养状态评分与肝细胞癌肝切除术后预后的研究进展

肝细胞癌(HCC)是最常见的恶性肿瘤之一。尽管在早期诊断和个体化治疗方面取得了进展,但经根治性切除等治疗后,HCC患者的临床预后仍不佳,复发率高。因此,在HCC患者中识别准确可靠的预后标志物是必要的。作为一种新的免疫营养生物标志物,控制营养状态(CONUT)评分已被报道用于预测癌症患者的预后。本文将对术前CONUT评分与HCC肝切除术后预后的研究进展进行综述。     

腹部超声联合阴道灌注0.9%氯化钠诊断幼女阴道异物的临床价值

目的 分析腹部超声联合阴道灌注0.9%氯化钠对幼女阴道异物的诊断价值。方法 回顾性分析2018年1月—2021年12月就诊于赣州市妇幼保健院妇科的102例疑似阴道异物幼女临床资料。患儿均接受经腹部超声、阴道灌注0.9%氯化钠检查。以宫腔镜诊治结果作为金标准，分析经腹部超声单独检测或腹部超声联合阴道灌注0.9%氯化钠诊断阴道异物的准确性、有效性。结果 宫腔镜结果显示，患儿中阴道炎有21例（20.59%），阴道异物有81例（79.42%），其中棉絮状物、谷物、头发丝等线状物最为常见；单独诊断、联合诊断出阴道异物分别有69例和79例，与宫腔镜诊断结果的K值分别为0.689和0.897。将宫腔镜诊断结果作为金标准，单独诊断、联合诊断阴道异物的敏感性分别为0.765（95% CI：0.594，0.816）、0.951（95% CI：0.826，0.995），特异性分别为0.667（95% CI：0.563，0.786）、0.905（95% CI：0.795，0.972），准确度分别为0.745（95% CI：0.586，0.813）、0.941（95% CI：0.817，0.984），单独诊断、联合诊断的敏感性、特异性、准确度可信区间无重叠，说明有统计学意义。结论 阴道灌注0.9%氯化钠可增强幼女阴道异物在超声下的显影，提升诊断准确性、有效性，且操作简单、损伤小，起到清洁阴道作用。     

基于DEA方法的华法林抗凝分级管理模式的效率评价

目的:通过小范围的临床实践,使用数据包络分析(data envelopment analysis,DEA)方法对基于全程化抗栓药学服务模式的华法林抗凝管理工作效率进行评价。方法:选取2021年7-12月南京大学医学院附属鼓楼医院心胸外科瓣膜置换术后使用华法林抗凝的患者。将患者分为实验组和对照组,实验组由临床药师利用基于分级管理的全程化抗栓药学服务模式进行抗凝管理和药学监护,对照组由临床药师按照无差别监护模式进行抗凝管理和监护,记录2种模式下药师工作内容和工作成效,通过DEA方法分析比较2种抗凝管理模式的效率。结果:研究最终纳入服用华法林的患者233人(实验组116人,对照组117人),实验组的单位患者管理时间显著减少[(27.8±9.7)min vs.(34.8±11.4)min]。经模型计算后,实验组的总体效率值为1,说明其投入和产出最优,且效率高于对照组。结论:全程化抗栓药学服务模式下药师管理单位抗凝患者需要的时间更少,管理效率更高。
